BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a heat generating device, and more particularly, to a device for generating heat by spraying liquid at high speed and high pressure that heat the liquid when it passes through a heat generating unit where its molecules are forced to collide one another, resulting in generating friction and resistance, thereby employing the heated liquid as a heat source for heating or hot water supplying.

2. Description of the Related Art

Conventionally, several known heat sources such as electricity, oil, gas, etc. are utilized for heating and the heat from the sources is used to supply hot water. Among the heat sources, oil or gas needs to be burned to function as heat sources, which causes environmental pollution in all its aspects like air, water, etc. To use only electricity as a heat source inevitably leads to the excessive consumption of electricity, especially in a certain season where the supply falls short of the demand. Besides, the source of the electricity is generated by burning natural energy like oil or gas. Thus, it is at present unavoidable to encounter the above-mentioned serious problems including environmental pollution.

SUMMARY OF THE INVENTION

It is an object of this invention to provide a device for generating heat by spraying liquid at high speed and high pressure that sprays the liquid into a heat generating unit where the molecules of the liquid collide against the walls thereof or the projections provided therein, thereby creating friction and resistance which cause the liquid to be heated, whereby the heated liquid can be utilized as a heat source including for heating or supplying hot water.

It is another object of this invention to provide a device for generating heat by spraying liquid at high speed and high pressure that is provided with a liquid circulating pump that is coupled on a liquid feeding pipe on the inlet thereof, a heat generating unit that is coupled with the outlet thereof, and a plurality of projections that are closely formed on the inner peripheral wall of the heat generating unit, whereby while the liquid is passed through the heat generating unit, the molecules of the liquid collide against the plurality of projections on the inner wall of the heat generating unit, resulting in the generation of friction and resistance therefrom that cause the liquid to be heated to high temperature.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

A preferred embodiment of the present invention will be described hereinbelow with reference to the accompanying drawings. In the following description, like reference numerals identify similar or identical elements throughout the several views, while well-known functions or constructions are not described in detail so as not to obscure the invention in unnecessary detail.

Referring to FIGS. 1 and 2(A) and (B), the construction of this invention contains the liquid circulating pump 10 that is coupled with the liquid feeding tube 11 via the inlet of the liquid circulating pump 10 and the heat generating unit 12 with the outlet of the liquid circulating pump 10. In this case, the heat generating unit 12 comprises two or more bends in a continuous, repetitive way and the plurality of projections 12 a that are closely formed therein. It is contemplated that any number of units 12 may be connected together with or without additional pumps 10. The heat generating unit 12 is a means to induce the liquid molecules to collide with one another for generating heat. The collision of the liquid molecules may be promoted by increasing the flowing speed of the liquid when the plurality of projections 12 a are created in every or every other heat generating unit 12. Otherwise, another tube having a smaller diameter than the heat generating unit 12 may be mounted within the heat generating unit 12, having the plurality of projections 12 a on the inner and outer circumferences thereof, respectively, such that the collision of the liquid molecules may be further accelerated. Ultimately, this invention relates to the efficiency to raise temperature depending on the amount of collisions among the liquid molecules. Any type of heat generating unit 12 may be employed as long as the projections 12 a are formed therein. In other words, the formation of the projections 12 a within the heat generating unit 12, irrespective of the type of the heat generating unit 12, may be involved in the scope of this invention. Furthermore, considering that the tube diameter and length of the heat generating unit 12 are a function of the capacity of the liquid circulating pump 10, they cannot be specified and therefore, after the liquid circulating pump 10 is first selected according to its purpose of use, they may be calculated and defined according to the capacity of the pump.

Referring to FIG. 3, the liquid circulating pump 10 is connected to the liquid feeding tube 11 supplying source liquid through the inlet thereof, and the heat generating unit 12 having a heat cover 21 thereon is connected with the outlet of pump 10. Unit 12 is [thereof] coupled to a secondary circulating pump 22 and a circulating valve 23. An air discharge outlet 27 is disposed in the rear outlet of the circulating valve 23 and a liquid passway tube 24 is disposed just in front of the air discharge outlet 27. The liquid passway tube 24 is connected to the liquid feeding tube 11, while liquid may be discharged through a discharge tube 28 with a liquid discharge outlet 29 by a liquid discharge valve 25 at a predetermined position. Under the above construction, if the source liquid is fed through the liquid feeding tube 11, the liquid has high speed and high pressure when it passes through the liquid circulating pump 10 and fed to the heat generating unit 12. The liquid collides against the walls and projections 12 a within the heat generating unit 12. In the meantime, the liquid molecules collide with one another to thereby create friction and resistance, resulting in an increase of the liquid temperature. Consequently, heat higher than the normal temperature is generated and kept constant with the heat cover 21 not radiating heat. The hot liquid at a higher than normal temperature may be discharged as hot air or hot liquid according to the direction of the circulating valve 23 via the circulating pump 22. At the time, the hot air discharged from the heat generating unit 12 by the circulating pump 22 is collected on the upper portion of the circulating pump 22 and the hot liquid discharged thereby is collected on the lower portion thereof. At this time, if the hot air is designed to be discharged to the air discharge outlet 27 at the time when the temperature thereof is sensed by a thermal sensor 26, this kind of construction will as a heater. On the other hand, the hot liquid may pass through the liquid passway tube 24 to forcedly return to the liquid feeding tube 11 and then pass through the liquid circulating pump 10 and the heat generating unit 12 again. Consequently, the liquid temperature increases higher than that before the liquid passes through the liquid passway tube 24. In this case, the liquid passway tube 24 can be utilized for the heating for houses and apartment complexes. And, supplying hot water may be available by opening the liquid discharge valve 25 of the liquid discharge tube 28 located on the side of the outlet of the liquid passway tube 24. The temperature generated from the liquid passway tube 24 depends on the capacity and tube diameter of the liquid circulating pump 10 and on the size and length of the heat generating unit 12.

A result of experiment on the present invention shows the changeable range of temperature as follows.

On the following conditions

Air temperature: 22° C.

Liquid circulating pump: 1.5 HP (horsepower)

Length & tube diameter of heat generating unit: L10 m×4 mm

Feeding temperature of source liquid: 16.5° C.

The changeable range of temperature is defined as follows:

TABLE 1 No. Time (minutes) Temperature 1  5 minutes later 26.5° C. 2 10 minutes later   33° C. 3 15 minutes later   38° C. 4 20 minutes later   42° C. 5 25 minutes later   46° C. 6 30 minutes later 48.5° C. 7 35 minutes later   50° C.

As appreciated from Table 1, it can be noted that the temperature increases greatly at first and the range thereof then decreases as time elapses. Anyway, it is concluded that the temperature rises according to the increase of time. When the temperature reaches a certain level, it rises slowly or stays at the same level because the heat loss caused by low air temperature increases. The liquid in the above experiment according to the present invention is embodied by using pure water (H₂O), but it may not be limited to water. As a matter of fact, other liquids may provide higher temperature than water and therefore, they can be applied for various fields needing a heat source.

Thus, this invention can be employed for heating by raising the liquid temperature higher than it's normal temperature when the liquid molecules are forced to collide with one another by a heat generating unit and thus be applied for a heater by discharging the resultant air generated when the temperature of the liquid increases and for supplying hot water by discharging the liquid in the course of heating.

While the invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
